Abstract
The paper presents a numerical simulation of a stagnant (suspending) gas slug in the Taylor flow fitted to the experimental conditions. The simulation is based on the unsteady model of k - ω SST (shear stress transport) turbulence. Simulation covers analysis of gas-and-liquid flow parameters in the zones ahead the slug, after the slug and for the liquid film. The study demonstrates a compliance between the experiment results and simulation regarding the liquid film shear stress, the slug nose shape and the film thickness.
